Monica Rose had a chat with People to reveal why she chose each look for some of Hollywood’s hottest ladies in truly statement-making styles.

When it comes to dressing the younger Jenner sister, Monica says, “Kylie definitely likes form-fitted stuff, but she’s definitely one that loves to take risks. She loves to wear a lot of streetwear brands and mix it in with high-end fashion. She’s pretty open.”

Because of that openness, Kylie is totally willing to step out in slay-worthy outfits like the sheer lace Balmain catsuit Kylie Jenner wore to her 19th birthday party in August. Monica says that because the event was held at a club, Kylie “wanted to be fun and sexy.” Achievement: unlocked.

For Kendall, the vibe is all about the ‘90s. Monica explains, “I grew up in the ’90s as a teenager so I feel like I always have a ’90s aesthetic.” *high-five* “The bralette was just so pretty, and I felt like, why not show it over the t-shirt and show how pretty it actually is? I just think she looks so cool and effortless.” And that’s just perfect for Kendall because, according to Monica, Kendall “just exudes coolness. She’s just so cool.”

For big sis Khloé, Monica feels like the best and boldest she’s done is the nude Balmain skirt, top and bodysuit. What’s surprising (or not?) is the fact that this is actually the toned-down version of what was originally planned. The first look was totally sheer. But considering this was for an appearance on Ellen, we think adding the slip was definitely the right choice. “I thought since it was for Ellen and since it was daytime, we had to add a slip on it and not make it so sexy, so ‘night.’” Takeaway: One amazing outfit can work two ways, if you just add a slip.
